In the bathroom heating clothes dryer A, when the heater is overheated due to dust clogging during the high speed drying operation or the standard drying operation, the heater and the heater peripheral equipment are automatically cooled. The procedure of automatic cooling of the heater and heater peripheral equipment will be described below based on the flowchart of FIG. When the user turns on any of the operation switches 41 to 43 of the operation operation panel, the drying operation set by the user via the operation switches 41 to 43 is started (S1). The drying control circuit 31a determines whether the operating state is the high speed drying operation or the standard drying operation (S2). When the operating state is neither the high speed drying operation nor the standard drying operation, that is, when the operating state is the blast drying operation, neither the first heater 7a nor the second heater 7b is operating and overheats. Since there is no fear, unless the operation switches 41 to 43 are all OFF, the set drying operation state is maintained by the drying control circuit 31a (S2, S3, S1). When all the operation switches 41 to 43 are turned off by the operation of the user, the operation ends (S3, S4).

When the operating state is the high speed drying operation or the standard drying operation, that is, when the first heater 7a and the second heater 7b are operating or the first heater 7a is operating, The drying control circuit 31a determines whether the heater ambient temperature T detected by the temperature sensor 8 is equal to or higher than the first set value T1 (S2, S5). When the heater ambient temperature T is lower than the first set value T1, the first heater 7a and the second heater 7b are not overheated, so that the set drying is performed unless all the operation switches 41 to 43 are OFF. The operating state is maintained by the drying control circuit 31a (S5, S3, S1). When all the operation switches 41 to 43 are turned off by the operation of the user, the operation ends (S3, S4).

When the heater ambient temperature T is equal to or higher than the first set value T1, the first heater 7a and the second heater 7b are overheated, or the first heater 7a is overheated, so that the operation state storage circuit. The operating state is stored by 31d (S6),
By the drying control circuit 31a, the alarm display lamp 50 is turned on via the output display circuit 31e, and the occurrence of abnormality is surely transmitted to the user (S7). Drying control circuit 31a
Thus, when the operating state is the high speed drying operation, the operation of both the first heater 7a and the second heater 7b is stopped, and when the operating state is the standard dry operation, the operation of the first heater 7a is stopped ( S8). The operations of the exhaust multilayer disc fan 13 and the swash plate type airflow direction changing device 20 are also stopped. The operation of the multilayer disc fan 3 for circulating hot air is continued. As a result, the overheated first heater 7a, the second heater 7b, or the overheated first heater 7a and the devices around the heater are quickly swept by the high-speed air or the low-speed air discharged from the warm-air circulating multilayer disk fan 3. To be cooled. As a result, it is possible to prevent deterioration and breakdown of devices around the heater.

The timer circuit 3 is controlled by the drying control circuit 31a.
1c is turned on, and counting of the elapsed time t from the time when the operation of the first heater 7a and the second heater 7b is stopped or the time when the operation of the first heater 7a is stopped is started (S
9). The drying control circuit 31a determines whether the heater ambient temperature T is equal to or lower than the second set value T2 (S1).
0). The second set value T2 is set to a value lower than the first set value T1 in order to prevent hunting. If the heater ambient temperature T has not dropped to the second set value T2, the drying control circuit 31a causes the first heater 7a and the second heater 7a to
When the operation of the heater 7b is stopped, or the first heater 7a
It is determined whether or not the elapsed time t from the time when the operation of (3) has stopped reaches the predetermined value t1 (S11). The predetermined value t1 is
It is the time required for the overheated heater to cool to a predetermined temperature, which is experimentally determined. If the elapsed time t has not reached the predetermined value t1, the dry control circuit 31a causes the current operation switches 41 to 43 to be in the ON or OFF state, that is, the currently set operating state and the operating state storage circuit. The operating state stored in 31d is compared to determine whether the operating state has been changed, that is, whether the operation switches 41 to 43 have been operated by the user after the cooling of the heater was started (S12). ). When the operating state is changed, that is, when the user operates the operation switches 41 to 43 after the cooling of the heater is started, the heater ambient temperature T is again set after the alarm display lamp 50 is turned off. It is determined whether or not it is equal to or less than the second set value T2, and if not, the alarm display lamp 50
It is determined again whether or not the heater ambient temperature T is equal to or lower than the second set value T2 while maintaining the lighting of (S12, S1).
3, S10). The alarm display lamp 50 is kept lit until the user operates the operation switches 41 to 43, so that the occurrence of the abnormality is reliably transmitted to the user.

When the heater ambient temperature T drops to the second set value T2, or when the elapsed time t from when the heater is turned off reaches a predetermined value t1, the overheated first heater 7a and second heater 7a 7b or the overheated first heater 7a
Since the heater peripheral equipment is cooled to an appropriate temperature, the drying control circuit 31a turns off the timer circuit 31c and resets the count value to 0 (S1).
4). Until the heater ambient temperature T decreases to the second set value T2, or until the elapsed time t from the time when the heater is turned off reaches a predetermined value t1, the overheated first heater 7a and the second heater 7b are stopped. Since the operation stop state of the first heater 7a that is maintained or overheated is maintained and the operation of the multilayer disc fan 3 for warm air circulation is continued, the overheated first heater 7a and second heater 7b, or overheat Done first
The heater 7a and the heater peripheral devices are surely cooled to an appropriate temperature.

Current operation switches 41 to 43 are turned on and off
FF state, that is, the currently set operating state,
The operating state stored in the operating state storage circuit 31d is compared, and whether or not the operating state has been changed, that is, after the cooling of the heater is started, the user operates the operation switch 41.
~ 43 is operated, then it is determined whether the alarm display lamp is OFF, if the operating state is changed and the alarm display lamp is still ON, the alarm display lamp Turned off (S
15, S16, S17). The user operates the operation switches 41 to 41.
Since the alarm display lamp 50 is kept on until the user operates 43, the occurrence of abnormality is surely transmitted to the user. When the operating state has not been changed, the lighting state of the alarm display lamp is continued (S15), and the occurrence of the abnormality is reliably transmitted to the user. When the operating state is changed and the alarm display lamp is off, the off state of the alarm display lamp is maintained (S15, S1).
6).

It is determined whether all the operation switches 41 to 43 are OFF (S18). Unless all the operation switches 41 to 43 are OFF, the operation of the bathroom heating clothes dryer A is started in the currently set drying operation state (S
18, S1). After the overheated heater and the heater peripherals are cooled to an appropriate temperature, the bathroom heating clothes dryer A is automatically started to operate in the currently set drying operation state, so that the user's latest The drying work is restarted under the intended operating conditions. This improves usability of the bathroom heating clothes dryer A. Operation switches 41-43
If all are OFF, the operation ends (S18, S
